Abstract

This study was carried out to determine the efficiency using applied P under a conventional recommended fertilization regime in pineapple cultivation with residue removal. Results showed that P recovery from applied P fertilizer in pineapple cultivation on tropical peat soil was 53%. At 0-10 cm depth, there was a sharp decrease of soil total P, extractable P and soil solution P, days after planting for plots with P fertilizer. This decline continued till the end of the study. Soil total, extractable and solution P at the end of the study were generally equal to those before the study. There was no significant accumulation of P at 10-25 and 25-45 cm depths. However, P concentrations throughout the study period were generally lower or equal to their initial status. Recovery of P in pineapple cultivation on tropical peat soil seems to relate to P loss. As such, P loss needs to be considered in fertilizer recommendations for pineapple cultivation in organic soils.
